SAND DEWATERING DEVICE AND METHOD

A dewatering device for aggregate products such as sand and gravel to allow dewatering to a moisture within the range of 8% by weight. This energy efficient dewatering system uses an inclined rotatably mounted dewatering screw (12) to initially dewater, followed by an associated vibratory dewatering...

Zusammenfassung:	A dewatering device for aggregate products such as sand and gravel to allow dewatering to a moisture within the range of 8% by weight. This energy efficient dewatering system uses an inclined rotatably mounted dewatering screw (12) to initially dewater, followed by an associated vibratory dewatering screen (46) to achieve combined results that neither an inclined dewatering screw or a vibratory screen can achieve separately. L'invention porte sur un dispositif de déshydratation de produits en agrégats tels que le sable et le gravier qui permet de ramener leur teneur en eau aux environs de 8% en poids. Ce système de déshydratation peu énergivore utilise d'abord une vis de déshydratation rotative inclinée (12), puis un crible vibrant associé (46), ce qui permet d'obtenir des résultats que la vis où le crible ne peuvent atteindre lorsqu'ils sont utilisés séparément.
